1 Scope This European Standard introduces general requirements on video transmission. A detailed specification on analog video transmission over different media including signal and performance requirements is already defined in prEN 50132‑5‑3. For the growing number of surveillance applications based on IP video transmission the requirements are defined in 2 standards. This standard covers in the following clauses the general requirements for video transmissions on performance, security and conformance to basic IP connectivity, based on available, well-known, international standards. In areas where more detailed IP requirements are necessary additional specifications are given, in order to reach compatibility. In this European Standard no detailed and special CCTV protocols are defined. In Part 2 of this European Standard, a detailed video IP protocol , messages and commands on top of the general connectivity and performance requirements of Part 1 are defined. Part 2 defines an IP protocol for full interoperability (e.g. PTZ control, eventing, etc.) of video transmission devices used in surveillance applications. The first section of this standard defines the minimum performance requirements on video transmission for security applications in IP networks. In surveillance applications, the requirements on timing, quality and availability are strict and defined in the last section of this standard. Guidelines for network architecture on how these requirements can be fulfilled are given. The second section of this European Standard defines requirements on basic IP connectivity of video transmission de...
